Toxicology SIG

Our mission statement:

To provide a forum to discuss the statistical issues involved in Regulatory and Investigative Toxicology.

Our membership consists of statisticians at CROs, pharmaceutical companies and academia who are working in preclinical areas such as:

- Acute Tox
- General Tox
- Toxicokinetics
- Repro Tox
- Genetic Tox
- Immuno Tox
- Toxicogenomics
- Histopathology
- Safety Pharmacology
- Carcinogenicity

We discuss topics ranging from Dog Telemetry data analysis to Decision Trees, from Bayesian methods to dealing with irate study directors, and no have a list of over 40 affiliates on our e-mail distribution list.
Join our mailing list by e-mailing this address with brief details of the field(s) you are working in.


In March 2017 we ran our latest Workshop, at the Crowne Plaza Hotel near Heathrow. The agenda focused on five hot topics in Toxicology: 

  • Repeated measures for Toxicology
  • Historical Control Data/outliers/control charts
  • Outlier determination
  • Carcinogenicity studies
  • How do we empower scientists to do routine analyses, whilst still ensuring quality of results?

Since our inauguration in 2006 we have run these workshops approximately every 18 months. We plan on running the next workshop on the 24th and 25th April 2018 at the Crowne Plaza Hotel, Heathrow, UK. More details to follow shortly.
